The Bem Sex Role Inventory consists of 20 items that represent typically male characteristics, 20 representing typically female characteristics and 20 representing neutral characteristics.
Participants rate their own personality on a 7-point Likert scale, which is then measured across the two dimensions of androgyny (or undifferentiated) and masculinity (or femininity).
Androgyny is a type of gender and so can be considered a social construct, making it a very subjective idea and each individual will have differing opinions about the extent to which they are androgynous.
Bem’s BSRI may be considered an over-simplification of such a complex and subjective social construct as gender, as suggested by Golombok and Fivush (1994).
Golombok and Fivush suggested that the BSRI does not consider smaller, but still important, aspects of gender and androgyny, such as a person’s interests.
The Personal Attribute Questionnaire (PAQ) may be a more suitable alternative to the BSRI, as it measures personality along different, but more ‘personal’ dimensions i.e. expressivity and instrumentality.
